Sean Rafferty with highlights from across the week on In Tune. American opera star, Joyce DiDonato, came in to talk about her new disc and why she is so passionate about it, Jools Holland was in the studio telling us about his duets al fresco with birds on the Kent marshes, conductors Rumon Gamba and Scott Dunn on why Richard Rodney Bennett was such a special composer, and the home-grown talent that is mezzo-soprano Sarah Connolly gave us some Britten along with Joseph Middleton on piano.
